9 Claims.

lfhis invention relates to mechanisms .for type setting machines. Insuch machines it is customary to provide a plurality of magazines eachcontaining types of a different size, and a corresponding number ofmolds each-adapted to receive types from one of the magazines. Beforethe ma chine is used the magazine containing the types of the sizerequired is set at its type-discharging position and the correspondingmold is set at its type-receiving position, for if the wrong mold isleft in type-receiving position the result will not be satisfactory.However as these two operations are now entirely separate and distinct,and depend upon separate adjustments made by the operator, it notinfrequently happens that synchronizing adjustments are not made withthe result that the proper mold is not is position to receive the typedischarged from the magazine in operative position.

This invention aims, among other things, to

provide a mechanism for type setting machines through which movement ofthe magazines to bring any one of them to-its type-discharging positionsimultaneously moves the molds so that the mold corresponding to thatmagazine is brought to its type-receivingstation.

Another object of the invention is to provide such a mechanism which isso arranged that upon arrival of any one of the magazines at itstypedischarging position the drive means through which the molds arerotated by movement of the magazines is automatically disconnectedthereby permitting rotation of the molds without impartting any movementto the magazines. This is necessary because from time to time during useof amold it has to be turned from its type-receiving to its type-castingposition and back to its typereceiving position. However during thesemovements errors in adjustment of the molds relative tn their magazinesare not likely to occur.

A further object of the invention is to provide a mechanism for typesetting machines for controlling the setting of the molds by movement ofthe magazines which may either be built into a machine or applied to amachine already in use.

Having thus briefly and broadly-stated some-of the objects andadvantages of the invention I will now proceed to describe it indetailwith the aid of the accompanying drawings, in which:

Figure 16 is a side view in the direction of the arrow I6 in Figure 15and includes also the chain drive to the lower sprocket wheel.

I will first describe the parts of a conventional type setting machinewith which my invention cooperates, as it is of course realized thatsuch a machine performs various operations, such as selectivelydelivering types to the mold in posi tion to receive them, type castingand theiike, all of which has no bearing on my mechanism, so the meansemployed .for so doing is largely ignored both in the drawings and thespecificationfor the sake of both clarity and brevity.

Provided upon the upper part of the machine are a plurality of parallel,vertically spaced magazines, 2, 3, A and 5 which are downwardly inclinedtoward their front extremities and are relatively downwardly and.rearwardly stepped at their ends. These magazines are .held in parallelspaced relation as by strapsfi. Integral with opposite sides of theframe I of the machine are substantially horizontal arms 1 slotted at 8.in-termediately of their length and extending along the lower faces ofthe slots are racks 9. Extending transversely of the machine beneath thebottom magazine 5 and through the slots 8 is a crankshaft l0 havingpinions ll fixed thereon which engage the racks 9, and the It) not onlyis the latter moved longitudinally in the slots 8 by engagement of thepinions I with the racks 9 thereby moving the magazines 2, 3, 4 and 5forwardly-or rearwardly, but the said magazines are also raised orlowered by the crank shaft H]. In this manner the lower discharge end ofany one of the magazines may be brought into registry with the upper endof a chute |4. Fixed on the crank shaft I is a sprocket wheel l having achain l6 passing around it which also passes around an intermediatesprocket l7, and mounted coaxially with the latter for rotationtherewith is another sprocket wheel l8 around which another chain l9passes which also extends around a sprocket wheel fixed on a spindle 2|which is turned through a crank handle 22. which the ends of the crankshaft l0 extend are provided at their opposite extremities with rollers24 which ride along substantially horizontal guides 25 formed upon therear upper portions of the arms 1 as the crank shaft is rotated.

Mounted beneath the magazines 2, 3, 4 and 5 at right angles to the axisof the crank shaft I0 is a horizontal shaft 25 having a ring gear 26thereon which supports four molds 21, 28, 29 and 39 arrangedsubstantially to form four sides of a square though with theirextremities spaced from one another. From the chute 4 types aredelivered by a conventional delivery means indicated at Ma to whichevermold is at that time located at the position a. If therefore the molds2T, 23, 29 and 30 are designed to receive types from the magazines 2, 3,4 and 5 respectively when the magazine 5 is in position to dischargetypes into the chute M the mold 39 is at the position a to receive it.Mounted on themachine is a drive shaft 3| having an axially'movable gear32 freely mounted thereon which always remains in mesh with ring'gear26. Fixed on the shaft 3| is a disc 33 having a forwardly projectingdrive pin 34 to engage an aperture 35 formed in the rear face of thegear 32 and drive the latter. Formed integral with thegear 32 is anannular axial projection 36 which extends forwardly around the shaft 3|and terminates at its front extremity in a flange 31 of increaseddiameter. The projection 36 is also provided with spring means 36atending to retain the gear 32 at its rearward position shown and engagedby the driving pin 35.

The purpose of the invention is to provide an attachment for corelatingthe rotation of the ring gear 26 with the movement of the magazines 2,3, 4 and 5 so that if one of the latter is positioned to discharge typesinto the chute I4 and the proper mold 27, 26, 29 or 30 is in theposition a to receive the types, any subsequent adjustment made to moveanother magazine to type-discharging position will also move thecorresponding mold to its type-receiving station; however the attachmentis so constructed and Links 23 through gear 4| and mounted for both freerotation and axial movement on the other extremity of the shaft 40 is agear 42 having a grooved collar 43 integral with its rear face and anaperture 44 formed in its front face. Fixed also upon the shaft 49 infront of the gear 42 is a collar 45 having a driving pin 46 projectingtoward the gear 42 and adapted to engage the aperture 44. Between thegear 42 and the collar 45 a sprin 41 is provided which tends to retainthe collar 43 integral with the gear 42 in contact with one of thebearings 39 and the said gear spaced from the collar 45 so that thedriving pin 46 is disengaged from the aperture 44.

Mounted also upon the frame I are other bearings 48 which support ashaft 49 having a sprocket wheel 50 and a gear 5| fixed thereon. Thegear 5| meshes with the gear 4| and formed on its arranged that the ringgear 26 and its molds 21,

yokes 56 and 51.

front face is an annular cam 52 which is flat around the major portionof its circumference and is provided'with one relatively sudden, narrowdepression 53. Mounted for axial movement in bearings 54 is a rod 55 oneextremity of which bears against the cam 52 and provided on the oppositeextremity of the rod are two shifter The yoke 56 engages the groovedcollar 43 and the yoke 51 bears against the rear face of the flange 38,so that forward movement of the rod 55, through the yokes, moves thegear 42 into engagement with the driving pin 46 whereupon the said gearturns with the shaft 40, and also disengages the gear 32 from thedriving pin 35 so that the said gear 32 may turn freely upon the shaft3|.

A pin which forms the axle for one of the rollers 24 also extendsthrough a member 58 having a rack 59 on its underside, thereby pivotallyconnecting the said member to one of the links 23. Formed longitudinallythrough the member 58 intermediately of its length is a slot 6| having aroller 62 mounted for rotation therein, and extending from an upright 63mounted on the frame I is a brace 64 on the outer extremity of which theroller 62 is rotatably secured. Thus the brace 64 and roller 62 serve tosupport the extremity of the member 58 remote from the roller 24 andpermit movement of the said member as the roller 24 travels along itsguide 25.

Mounted also on the frame I is a bracket 65 integral with which are twobearings 66 and 61 arranged at right angles to one another.' The bearing66 supports a shaft 68 having a sprocket wheel 69 and a bevel gear 16fixed thereon, and the bearing 61 supports a shaft 1| having a bevelgear 12 thereon which meshes with the bevel gear 19 and a pinion 13which engages the rack 59. A chain 14 extends around the sprocket wheels69 and 50 to impart a drive from the shaft 68 to the shaft 49. l

From the foregoing it will be clearly seen that movement of themagazines 2, 3, 4 and 5 through their conventional operating mechanismincluding the crank handle 22 causes movement of the rollers 24' alongtheir guides 25. When this occurs the member 58 is also moved so thatits rack 59 turns the pinion 13. Rotation of this pinion through thegearing just described turns the sprocket wheel 69 thereby driving theshaft 49 and gear 5| through the chain 14 and sprocket wheel 59. Thisdrive is so'proportioned that each time one of the magazines reaches itstype-discharging position the gear 5| is so positioned that thedepression 53 in the cam52 is engaged by the rod 55 which is held incontact with the cam by the flange 31 which is rearwardly urged "by the:spring means 38m. When the rod .55 is in its rearward position the gear42 is pulled back out of engagement with the driving pin 46 by the yoke'55 and the yoke 57, when in .its arearward ner that it will notinteriere with the operati of other parts of the machine.

While in :the foregoing the preferred embodiments of the invention havebeen described and position, allows the gear 32 to move .rearwardlyshown itisunders'tooid that alterations and modiinto engagement with itsdriving pin .35. The "drive means is also so'proportioned that each timeone of the magazines reaches its type-discharging position the moldwhichcooperates withthat magazine is at its type-receiving station, Whenit is desired to turn the gear 32 by hand on its shaft 3| to turn one ofthe molds from its typereceiving to its type-casting position, or viceversa, it is merely necessary to pull the projection 36 forward andthereby disengage the gear 32 from its driving pin '35. Then rotation ofthe gear 32 also turnsthe gear 42 which at that tim is free on'its shaft40.

As soon as the magazines 2, 3, 4 and 5 commence to move the gear 5|commences to turn and the rod is disengaged from the depression 53 byrotation of the cam 52 and is moved forwardly. The yoke 55 moves thegear 42 into engagement with the driving pin 46 and the yoke 5'! movesthe gear 42 out of engagement with the driving pin 35. Consequentlyrotation imparted through the gear 5| turns the shaft 40, the gear 42,and the ring gear 25 through the gear 32 which is then free to rotate onthe drive shaft 31.

In Figures 14, 15 and 16 a modified and well known arrangement foradjusting the positions of the magazines 2a, 3a 4a and 5a to set any onestance an imaginary line extending across the ends of all the magazinesat either extremity is parallel with the axis of the post 80. on thelatter is a'rack 8| meshing with which is a pinion 82 fixed on a shaft83 that also has a worm wheel 84 thereon. In engagement with the latteris a worm 85 on a spindle 86 which is connected to other spindles 81 and88 through universal connections 89 and 90 respectively. Upon thespindle 88 is a crank 9| by rotation of which the spindles 88, 81 and 86are turned thereby Provided turning the worm 85, the worm wheel 84, and

the pinion 82 thus moving the rack BI and post 80 longitudinally so thatany one of the magazines may be brought into registry with the chute Mb.

In this instance a rack 59a. is secured to one side of the magazinesparallel with the path of movement of the post 89. This rack 59a isengaged by a pinion 13a mounted on a shaft Ha supported by a bearing 61acarried on a bracket 65a which also has a second bearing 86a thereon.Fixed also on the shaftlla is a bevel gear 12a which meshes with asecond bevel gear 19a on a shaft 68a supported in the bearing 65a.Secured also around the shaft 68a is a sprocket wheel 69a which drivesthe sprocket wheel 59 on the shaft 49 through a chain 14a.

It will be noted in the drawings that the chain 14, or 14a, is shownpassing around guide sprockets 94 mounted on suitable supports 95.Obviously any desired arrangement of guide sprockets may be utilized tocarry the chain in such a manflcations may be made thereto provided thesaid alterations and modifications fall within the scope of the appendedclaims.
